IMPROVEMENT IN TRUCKS.

Specification forming part of Letters Patent No. 122,686, dated January9, 1872.

SPECIFICATION.

We, ANTHONY VAN HAAGEN and JOHN H. COOPER, both of Philadelphia, countyof Philadelphia, State of Pennsylvania, have invented an Improvement inTrucks, of which the following is a specification:

My invention consists of a truck constructed in the peculiar manner toofully explained hereafter to need preliminary description, the truckbeing designed for the conveyance from place to place of blocks of soap,marble, stone, packages, &c., with the view of saving much of the labordemanded in moving such articles with ordinary trucks.

Figure 1 is a side View of our improved truck; Fig. 2, a plan view; andFig. 3, a vertical section of the lower portion of the truck on the line1 2, Fig. 1.

The frame of the truck consists of the op posite sides A and A,connected together by the front, 13, but disconnected at the rear, thewhole being, in the present instance, cast in one piece. To each side ofthe frame, near the rear end of the same, is hung a pin, D, on which isloosely hung a wheel, E, the rear of the truck being supported by thesewheels E, and the front of the truck on a smaller wheel, F, hung to theforked end of a vertical spindle, G, which turns in a projection, a, onthe front end of the frame, the spindle being furnished with a suitableshaft, H, by which the truck is guided and drawn over the ground. Tworods, I I, are arranged to slide and turn in, and are guided by lugs b bon each side of the frame, the rods also passing through.

projections 61 d on a plate, J, above which plate each rod has a collar,6, and handle f,- and the lower end of each rod is provided with a plateor arm, h, which, by turning the said V rod, can be moved to a positionbeneath the object to be lifted, as shown in Fig. 3, or can be moved onone side, so as to be clear of the said object. The vertical position ofthe plates J, and consequently of the rods I I and of the load, iscontrolled by bell-crank levers K, one lever being hung to a pin, 4., oneach side of the frame, and each plate J bearing upon a roller at theend of the short arm of one of the levers, as shown in Fig. 1.

Our improved truck, although well adapted to the moving about from placeto place of the truck is so backed that the opposite sides I of theframe will be on opposite sides of the block, the plates h having beenpreviously moved outward by turning the rods I I, and the plate J, withthe said rods and plates, having been lowered by raising the long arm ofthe lever K to the position shown by dotted lines.

The truck having been adjusted to the position shown in Fig. 2, inrespect to the block X of soap, the plates or arms h are so turned as totake their places beneath the board M, and the opposite levers K K arethen simultaneously depressed, thereby causing the short arms of thesame to elevate the sliding plates J and with them the rods I I and theblock of soap, to an altitude determined by a stop, :0, formed on eachplate, with which stop the roller on the short arm of the lever comes incontact, as shown in Fig. 1. hen the levers are in this position theirshort arms are so inclined from the perpendicular, that, resting againstthe stop on the plates J, they serve to support the block of soap, theWeight of which cannot disturb the levers.

The block being now supported by the truck may be moved with the latterto the desired position on the floor, when, by elevating the long armsof the levers K, the block can be lowered until the board M is incontact with the floor, when the truck, after turning the arms h houtward, is at liberty to be used in moving another block. A horizontalbar, 02, supported by rods 10 and stayed by diagonal rods q, serves as ahandle, by which attendants can aid theman at the shaft H in drawing thetruck and its load over the floor.

It will be evident that the truck can be used for conveying blocks ofmarble or stone, cases of dry goods, 850., from place to place.

It will also be evident that by combining a 7 equivalents, through themedium of which the said arms h k can be raised or lowered.

3. The combination of the said sliding plate J and its stop a: with thebell-crank lever K.

In testimony whereof we have hereunto set our hands in the presence oftwo subscribing witnesses.
